We bought the duo. The wife and I enjoy both very much. The smaller piece is fun to carry around and is super palm friendly. The big boy "oh man that holds alot", is our go to with a Mega or Terpcicle. With or without water the sesh is smooth and tasty. I would recommend a checking out the tube if you want to see it in action. Also this might seem trivial but thank you Vgoodiez for not marking up the glass with a logo. That is what a sweet looking Vgoodiez moodmat is for :)
Absolutely awsome. I use my Mega for my Terp Hammer, Pinch Hitter, as well as bonging my Mighty Plus using a WPA with hose that allows me to keep it upright; the way it was designed. Very hard to go back to traditional bongs after using this. Worth every penny.
I bought the 2 pc set.
The 5" Mega is now my desktop center bubbler.
The smaller 4" Cell is nice for around the house.
They came with more adapter glass than I know what to do with (at the moment ;) ).
With the correct device adapters, both Cells & whips work well providing smoother pulls with all 4 of my Dry Herb Vapes:
